The reflector that accesses terminal of multicarrier of emission when supposing support more than a carrier wave is to be limited to utilize a power amplifier, as the situation of the reflector of Fig. 3.Emission has following restriction when also supposing the multicarrier that comes self terminal:
There is predetermined restriction (" maximum transmission power ") in the amount of the power that can have multi-carrier signal.The restriction that should be scheduled to for example is the restriction that comes from terminal power capacity and spectral emission.Like this, transmitting power must be distributed in multicarrier.
In multicarrier, there is priority for the distribution of transmitting power.Thereby, the carrier wave with limit priority on its accessible power level without limits, up to its predetermined restriction.Carrier wave next and lower priority will be assigned with the handlebar maximum transmit power level and deduct the carrier wave transmission power afterwards of distributing to higher priority.
With reference to figure 2, power detector 221 is provided at the measurement of analog signal power of the output of power amplifier 215, processor 225 is carried out by administration behaviour, for example is by the emission restriction of stating among the above-mentioned IS-98D, the compensation of desired transmit power level (back-off).Power detector can use in the multicarrier shown in Fig. 3, single power amplifier reflector, with the restricting data carrier power, so that can put on above-mentioned restriction.Following description is illustrative embodiment, wherein transmitting power is to distribute between two carrier waves, wherein first carrier (being to be used for speech business in this example) has the highest priority, and second carrier wave (being to be used for data communication in this example) has next priority.This example is auxiliary as the priorization distribution principle of explaining transmitting power, is not to be limited to two carrier waves to the application of these principles, and is limited to the carrier wave precedence scheme that voice carrier always meets limit priority.In fact, priority algorithm described below can be adapted at surpassing in two the carrier wave and distribute transmitting power, and this is based on the problem that priority is design alternative.In addition, this example comes principle of specification with the terminal with single power amplifier.This explanation is not must serve under the condition of a plurality of carrier waves that can be launched simultaneously but these principles are applied to single power amplifier with the application limitations of these principles to the terminal with single power amplifier.
Power amplifier headroom algorithm (headroom algorithm) can be realized in the data carrier terminal, with computing terminal missile maximum data rate on reverse link.This algorithm can be carried out by the DSP as the processor among Fig. 3 365.The first upper limit of considering at the power of reverse-link data channel pilot signal of algorithm:
The pilot power upper limit (dB)=LPFTxOpenLoop+PeakFilterTxClosedLoop+Margin
(1)
Equation (1) has defined the upper limit of the available launch power amount of distributing to pilot channel in the data back link.The LPFTxOpenLoop composition is the low-pass filter value of measuring in the open Loop Power control processing procedure.The PeakFilterTxClosedLoop composition is the peak filtering value that obtains in the closed power control and treatment process.The Margin composition provides the upper limit for the pilot channel the packet of launching on the reverse link whole the duration; Level that this value can be set to be scheduled to or dynamically change are with the adaptive channel condition.The filter type that the acquisition open loop is used with the closed loop composition is different.The low pass filter of instantaneous value is used to obtain the open Loop Power control value, is used to obtain the closed power controlling value and have the peak filter of long die-away time.
Consider that available launch power is limited, and the fact that must in pilot tone, data, affirmation (ACK) and data rate control (DRC) channel, distribute, reverse-link data channel with the rate emissioning data suitable with available transmit power level to data channel.Can determine by channel gain at the available launch power of these channels with reference to the power level of pilot channel.Therefore, along with changes in channel conditions, power can be reallocated, and may cause requirement to change data rate.Following table has been summed up the link data speed about the requirement of relative power gain, and relative power gain is (DataChannelGain) about the pilot channel that can use data channel.
Figure G2009102526877D00101
Now, power amplifier (PA) headroom algorithm has provided the headroom of power amplifier at the emission of specific data rate, and wherein, actual value is (lin) in linear domain.
PAHeadroom(rate)＝MaxPower(lin)-[PilotPowerUpperBound(lin)*T2P(rate)] (2)
Note, although equation (1) is that the equation of equation (2) and back is to represent with linear term with nonlinear terms (dB) expression, auxiliary as to the understanding of the notion expressed.As understanding with reference to equation (2), the PA headroom calculates the transmitting power that the maximum power level limiting terminal can be launched with reference to maximum power level (MaxPower (lin)).As mentioned above, this restriction can be because battery capacity or because the combination of a plurality of factors simply.In any case, pilot channel power can be weighed, to consider other channel of being launched (data, ACK and DRC) relevant with data service.This is to consider these other channel by ratio T2P (speed), and this combines each relative gain of those channels of relevant pilot channel at specific data rate.Thereby:
T2P(rate)＝[1+DRCChGain+ACKChGain+DataChGain(rate)] (3)
Equation (3) is the gain that pilot channel power is converted to whole signal powers at all data traffic channels.Significantly, if PAHeadroom (speed)＞0, then data rate is missile.Because in this example, data service has lower priority than speech business, this headroom algorithm is changed a little, calculating maximum power, the power that the part of this maximum power transmitting power that to be first data carrier (compare priority is the second level with voice carrier) use about voice carrier in multicarrier, single power amplifier reflector can adopt at any time.
For example by calculating data carrier Power Limitation in multicarrier, the single power amplifier terminal according to algorithm as the DSP of processor 365, algorithm satisfies such restrictive condition, be that maximum transmission power is limited, and compare with any data carrier, give the available launch power of voice carrier higher priority.In other words, the residue of transmitting power after the available launch power that requires any data carrier of transmitting power to be dispensed on to offer the needed any part of voice carrier.This algorithm is considered the possibility (representing by the OP CODE that is input to the processor among Fig. 3) of user and system's select operating mode, has at least three kinds of patterns according to this algorithm: voice channel and at least one data channel are movable (voice/data); Having only voice channel is movable (having only voice); With having only data channel is movable (having only data).According to the carrier wave priority that algorithm is observed, the state of any data carrier is not considered in the control of the power of voice carrier; But the state of voice carrier is considered in the power control of any data carrier; In other words, voice carrier has higher priority than any data carrier in transmit power allocations.
In the voice/data operator scheme, there is the maximum transmission power (MaxTxPowerAnalog) of distributing to voice carrier.Usually, voice carrier does not use whole available launch power, and obsolete part is provided for data carrier, submits to the current power level of data pilot channel.The expression formula of distributing to the maximum amount of power of data carrier is:
MaxDataPower(lin)＝[MaxTxPowerAnalog-TxAnalogPower]+
[TxPilotPower(lin)*T2P(rate)]-MarginForVoice (4)
In this calculates, variable MaxTxPowerAnalog is the available maximum transmission power of multi-carrier signal, it is this power of distributing to voice carrier on the basis of priority, if voice channel is movable or connects the pattern of setting up, and on the basis of second priority, if have, after distribution, give the power of one or more data carrier to voice carrier.This variable can be a fixed value, for example is the worst condition of the desired transmitting power of voice carrier, maybe can be function, and it produces a value based on current operator scheme.For example, under voice channel was movable condition, having necessary restriction MaxTxPowerAnalog was 200mA (23dBm), as when the voice-and-data channel all is activity to the direct inspection of the transmit power level of multi-carrier signal.According to more detailed process, the value of MaxTxPowerAnalog can be used as voice carrier power level function and change.For example, if the power level of movable voice carrier is lower than 23dBm, total then loosen to the restriction of transmitting power may be useful, as long as can satisfy the spectral emission level of multi-carrier signal with two or more active channels.Can expect by deduct voice carrier power from MaxTxPowerAnalog the amount of the professional available transmitting power of calculated data simply.But variable TxAnalogPower for example is the transmitting power of being measured by power detector 361 in output place of Fig. 3 intermediate power amplifier 345, and this measures the total amount of the transmitting power of expression voice carrier and data carrier (if any) use.Therefore, the amount of the transmitting power that data carrier uses is calculated as the amount that only reduces the transmitting power of the transmitting power of distributing to the higher priority carrier wave by item [TxPilotPower (lin) * T2P (rate)] add-back to limit this.Variable TxPilotPower is the current power level of data pilot channel, and T2P is the ratio of current whole business to pilot tone.The MarginForVoice variable is the distribution of increase that gives the additional emission power of voice carrier, to avoid emission infringement prediction or known to the voice carrier frequency; This value can be that fix or definite by function.In case finish this calculating, the power level of data carrier can be provided with by processor 365 by the AGC gain signal that is provided to amplifier 327, by solving PA headroom equation, replaces MaxPower and specified data speed with MaxDataPower.
In having only the operator scheme of voice, processor 365 carries out voice carrier power control and calculates, and these results carry out by the gain that the AGC gain signal via the control input that is provided to amplifier 307 is provided with amplifier 307.Although terminal is to operate in having only the pattern of voice, the terminal use can call e-mail program.In case edited email message, the user activates " transmission mail " order, and the reverse-link data channel of carrying electronic mail service enters to connect sets up state, wherein will send one or more Access Probes on reverse link, with the activation data channel.In case activate this channel, then enter the voice/data pattern, and send email message.In such time, along with entering, data channel connects the state of setting up, prepare the data transmission of initialization by first data carrier, the emission of Access Probe is carried out in data modem unit 323 beginnings on first data channel of reverse link.Processor must calculate and the power level that data carrier is communicated by letter with current Access Probe is set now.In this case, following calculating MaxDataPower:
MaxDataPower(lin)＝[MaxTxPowerAnalog-TxAnalogPower]-MarginForVoice (5)
The value of calculating at MaxDataPower will be current Access Probe with the maximum power that is set up, this can be the suitable value that is provided with for the AGC gain of amplifier 327 by processor 365.
In having only the operator scheme of data, data channel is movable.Do not set up voice channel in the state in connection, processor 365 is provided with the power of data carrier according to above-mentioned equation (4), and the MarginForVoice component is set to 0.Although terminal is to operate in the pattern of having only data, the terminal use can begin typing telephone number, and it will make voice channel enter connection and set up state, will send one or more Access Probe in this state, with voice activated channel.But in this exemplary cases, terminal will not enter the voice/data pattern, activate " send and call out " order up to the user.When voice channel enters when setting up pattern, voice modem 303 sends and inserts mark (being input to the FLAG of the processor 365 among Fig. 3), and is ready for sending the Access Probe on voice channel.As the response to the access mark, processor 365 is maximum, solve equation, the also suitably gain of resonance-amplifier 327 by the MarginForVoice that is provided with in the equation (4), regulates and distributes the part to the transmitting power of data carrier.When reducing data carrier power when adapting to voice carrier, whether processor 365 utilizes PAHeadroom equation (2) to come the data rate of specified data channel must change.Change if desired, then signal to data modem unit 323 and change data rate on the reverse link data carrier wave.
Fig. 4 be illustrated in multicarrier access terminal in the priorization of the transmitting power method of distributing.Although with reference to the multiple carrier transmitter of figure 3, will whole flow processs of this method and independent action be described, this is just for easy understanding; In fact, this method can realize in many other multi-carrier terminals.In Fig. 4, supposing accesses terminal opens, and is in by in defined certain initial mode of operation of the OP MODE that is input to processor 365.Allow the START of this this method of conditional definition.When OP MODE when block diagram 402 changes, or terminal entered the voice-and-data business and all do not had initialized IDLE state, or the user of terminal has been chosen in the wherein professional initialized operator scheme of voice, data or voice-and-data.Under first kind of situation, this method is by judging that 404,406 and 408 are transformed into the IDLE state in the block diagram 410, and it is transformed into block diagram 402 when user's input operation code.When the input operation code, this method is also at first tested at the code of judging 404 from block diagram 402 conversions.If coded representation voice/data operator scheme obtains sure outlet from judging 404, make the distribution of transmitting power at block diagram 405 according to above-mentioned priority.That is to say that the gain of amplifier 307 is set to give the level of voice carrier with the professional necessary MaxTxPowerAnalog of support voice.Simultaneously, calculate MaxDataPower, and data carrier is set to the power level that calculates by the gain that amplifier 327 is set according to equation (4).This method keeps this condition, up to by user action or the changing of transformation operator scheme by some initialization system; In arbitrary situation, this method enters block diagram 402 once more.Suppose in the test of judging 404 and represent that operator scheme is not a voice/data that this method judges 406 by entering from the negative outlet of judging 404.If operator scheme is to have only speech pattern, obtain sure outlet from judging 406, this method enters block diagram 407.At block diagram 407, the gain of amplifier 307 is set to give the level of voice carrier with the professional necessary MaxTxPowerAnalog of support voice.Then, if the data Access Probe takes place, calculate MaxDataPower according to equation (5), if needed, the gain of resonance-amplifier 327 is offering data carrier from the MaxDataPower level that calculates.Otherwise this method is retained in the block diagram 407, if having need and as required, in response to the data Access Probe, change up to operator scheme, under these circumstances, this method is returned block diagram 402.Represent that operator scheme is not to have only voice if judge the test in 406, this method enters judges 408, and whether the test operation condition is data only.If the result of test is for affirming, this method is transformed into block diagram 409, determines MaxDataPower according to equation (4), and MarginForVoice is set to 0, and the gain of resonance-amplifier 307 if needed is offering data carrier from the MaxDataPower level that calculates.Then, if the voice Access Probe takes place, calculate MaxDataPower according to equation (4), MarginForVoice is set to big value, and the gain of resonance-amplifier 327 if needed is offering data carrier from the MaxDataPower level that calculates.Otherwise this method is retained in the block diagram 409, if needs are arranged and as required, the voice Access Probe is made response, changes up to operator scheme, and under these circumstances, this method is returned block diagram 402.
